FLOAT AND SINK TESTING APPARATUS.

Application filed April 26, 1924. Serial No. 709,286.

To all whom it may concern:

Be it known that I, GEORGE R. DELAMATER, a citizen of the United States, residing in the city of Lakewood, county of Cuyahoga,

and State of Ohio, have invented certain' In'iprovements in Float and Sink Testing Apparatus, of which the following is a specification.

My invention is an improved apparatus for separating and segregating constituents of different specific gravities comprised in materials to be tested. It is particularly applicable for use in separat ng and segrega ing slate and impurities from coal to determine the relative proportions of the car bonaceous and deleterious constituents, and for testing the efficiency of separation as it is performed in various washing devices.

My invention contemplates the separation of the several constituents by means of a solution of such specific gravity as to cause the heavier constituents ,to sink and the lighter constituents to float and it is the object of my invention to provide means for segregating and handling the constituents so separated in an efficient, expeditious and economical manner.

My invention relates particularly to the means for supporting and operating the sink collector, the float collector and the transfer device by which are eflected the segregation, collection and removal from the fluid of. constituentsseparated thereby. For this purpose, I preferably employ a vertically reciprocable bar or shaft having depending from the top thereof a tubular hanger which may be telescoped on and guided by a post or column within the fluid container. The hanger has fixed thereto a bracket provided with arms of suitable elasticity for detachably holding a sink collector and a float collector. A transfer device, revo-lubly connected with the reciprocable shaft and hanger, is movable along its axis of rotation by means of a. cam operable by a journaled shaft providing a lever for rotating the transfer device .so as to bring it into regis-- tration with the respective collectors.

The vertically reciprocable shaft may be conveniently operated through a geared connection with a revoluble shaft provided with a crank handle, and the reciprocable shaft and parts connected therewith may be held in desired position by suitable latching mechanism.

The characteristic features and advantages of my improvements will more fully appear from the following description and the accompanymgdrawings in illustration of an embodiment of my invention.

In the drawings, Fig. 1 is a top plan view dfapparatus embodying my invention; Fig. 2 is a vertical sectional view thereof on the line of Fi 1; Fig. 3 .is a transverse sectional view the apparatus, with a cover added thereto; Fig. 4 is a transverse section- :11 view of the operating mechanism on the line 44 of ig. 1; Fig. 5 is a partial transverse sectional view taken on the line 5-5 of Fig. 1; Fig. 6 is a fragmentary sectional view of the upper portion of the operating mechanism looking from the rear of the apparatus; and Fig. 7 is a fragmentary transverse sectional view of the construction shown in Fig. 6.

As illustrated in the drawings, fluid contamer or tank 1 is supported upon legs 2 and is provided "with the bottom'3 containing an aperture 4. A bracket 5 is fixed to the bottom 3 and has a hub 6 projecting through the aperture 4 into the tank. A tubular post or column 7, tightly sleeved on the boss 6, projects above the fluid level of the tank.

A shaft 8, provided with a crank-handle 9, is journalled in the bearing 10 and in the bearing 11 depending from the bracket 5. The shaft 8 has fixed thereon a gear wheel 12 which meshes with the rack 13. of a bar or shaft 14 splined in the bracket 5 and hub 6 and reciprocable through the shaft 8 by the rotation of the handle 9. The top of the shaft 14 has pinned thereto a flanged collar 15 from which depends a tubular hanger-16 telescoping over and guided by the tube 7.

A sleeve or collar 17 is telescoped on the top of the hanger 16, and has journalled therein a shaft 18 provided with an eccentric cam 19 contacting with the top of the shaft 14. The shaft 18 is revoluble about its axis by means of a handle 20 to rock the cam 19 and move the sleeve 17 vertically relatively to the tube 16, the shaft 18 also providing a lever for rotating the collar 17 on the hanger 16. The topof the tube 16 contains notches 16' in which the shaft 18 is seated when the collar 17 is in its lowermost position, whereby the positioning of the collar 17 relatively to the tube 16 may be accurately and easily determined.

The collar 17 has clamped thereto a 25 from the collector pans, and suc bracket 21 which has set therein a stud or screw 22-, which passes through the collar 17 into an arcuate slot 22 in the tube 16 to limit the rotation of the bracket 21 and sleeve 17, while ermitting vertical movement thereof by t 1e cam 19.

The bracket 21 is provided with the curved spring-arms 24 which embrace the periphery of the cylindrical rece tacle or transfer device 25 provided with t e annular ribs 26 which prevent vertical movement of the receptacle relatively to the bracket arms.

A bracket 27 is clamped upon the tube 16 below the plane of the bracket 21, and is provided with two sets of spring arms 28 which embrace the peripheries of the sievebottomed pans or collectors 29 between the annular ribs 29 thereon.

A shaft 30 is journalled in the bottom of the wall of the tank 1, parallel with the shaft 8, and has fixed thereto an arm 31 con- 4 nected by a link 32 with a latching slide 33 movable in a way 34 into and out of align-- ment with the rod 14. .The shaft 30 has the end thereof bent to form a handle 35 to provide means for rotating the shaft and operating the slide 34.

In the operation of my apparatus, the tank 1 is partly filled with a suitable solution, such as calcium or zinc chloride solution, of such specific gravity as to float a constituent of the material to be tested and permit the other constituent to sink.

The shaft 8 is operated by the handle 9 and acts through the pinion 12 and rack 13 to lower the rod 14 and the parts connected therewith so that the pans 29 are submerged and the receptacle 25 is immersed in the liquid in the container. By rotating the shaft 18 about its axis so as to rock the cam 19, the sleeve 17 and bracket 21 may be moved vertically to disengage the rece tacle receptacle may then be rotated about the axis of the ring 17 into registration with the pan which it is desired to use as the sink collector. The shaft 18 is then operated to lower the receptacle within the rim of the sink collector and the material to be tested placed in the receptacle. The heavier constituents, or sink of the material being tested will drop into the sink pan 29, while the light constituents, or float will float in the open-ended receptacle 25. When complete separation of the constituents has been effected, the handle 20, shaft 18 and cam 19 are rocked to disengage the receptacle 25 from the sink collector, and, by using the shaft 18 as a lever, the receptacle 25 is slowly rotated until it is in registrationwith the float collector which may be the other pan 29. The rocking of the cam 19 engages the receptacle and float pan together. The handle 9 is then rotated to elevate the shaft 14, which lifts the collector pans 29 and receptacle 25 above the surface of the fluid in the tank so that the constituents may be readily removed from the pans for testing. It will be observed that the receptacle 25 may be moved to engage or disengage the collector pans in all positions thereof.
